If you are looking for a video tutorial on how to get started using Node.js, then this is not the video for you. Unlike most of the O’Reilly training videos, this one puts theory far before practical development concerns, making it all but useless for practical study.
It should also be mentioned that Croucher is writing a book Node: Up and Running that may contain more practical samples. Perhaps he intends for the book and the video to be used in conjunction with one another?
I would not recommend this to a friend unless some more real-world or practical examples were added to the content.
